SPECIFICATION forming part of Letters Patent No. 654,757, datedJuly 31,1900.

' App ication filed January 13, 1900. Serial No. 1,260. (No model.)

To all whom it may concern.-

Be it known that I, JOHN G. OBnRMIEma citizen of the United States,residing at Canton, in the county of Stark and State of Ohio, haveinvented new and useful Improvements lowing is a specification.

My invention relates to stop blocks for lathes; and it consists inproviding an angle-.

plate carrying a number of adjustable headed screw-stops each to engagewith a tool-rest, so that a number of tool-rests may be mounted upon oneand the same machine and successively brought into operation by means oftheir respective cross-feeds without other adj ustinent than theprevious adjustment of the stop-blocks to the form of the work to beoperated upon, thus providing a multiple stopblock, as will behereinafter more fully described and claimed.

In the accompanying drawings similar letters of reference refer tosimilar parts.

Figure 1 represents a perspective View of my invention. Fig. 2 is across-sectional view.

A represents the bed-plate of the lathe, provided with the usualprojecting ways a, upon which there is mounted the slide-rest 13,carrying the adjustable tool-rest C, on which there is mounted thetool-head D. The toolrest 0 is capable of adjustment by meansof thecross-feed screw and leverE. These parts of the machine may be of any ofthe wellknown forms; but my invention consists in providing theangle-plate F, the lower flange of which may be securely engaged to theslide-rest by any of the well-known means; butIhave shown itfastenedthereto by means of the screw-bolts f. The upper flange of theangle-plate F is provided with a series of screw-threaded apertures f,which may be of any desired number, dependent upon the number of toolsto be operated. The headed screw-threaded bolt f is adapted to bemounted in the screw-threaded apertures f in the projecting flange ofthe angle-plate and is held in desired adj ustment therewith by means ofthe adj usting-nut f In operation the stopscrews are adjusted in theangle-plate at the desired points to stop'the tool-rest at the point atwhich it is desired to bring thetool into engagement with the work, andif a number of tools are to operate upon the same piece ther change oradjustment so long as work of the same form is to be reproduced.

Having thus fully described my invention, what I desire to secure andclaim by Letters Patent is- The combination in a lathe, of a bed-platowith a slide-rest mounted thereon, and carrying a tool-rest, cross-feedscrews engaging the slide and tool rest, an angle-plate mounted upon theopposite side of the rest, a series of screw-threaded apertures in theprojecting flange thereof,and headed stop-screws mounted therein andcarrying adj usting-nuts, substantially as described and for the purposeset forth.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
